[Column] Rising groundwater – 2 reasons why Tepco’s countermeasures may cause further disaster
Posted by Mochizuki on August 7th, 2013 · 2 Comments
The groundwater is estimated to reach the ground surface on 8/19/2013, which is the very urging problem.
On 8/7/2013, Tepco announced they are going to start pumping up the rising groundwater from 8/9/2013.
After pumping up the water, Tepco is going to discharge it to a shaft near the coastal line.
The shaft is connected to reactor2 turbine building through the trench.
The pumped up water would be over 100 tones a day.
The question is, Is it the right place to move the water ?
Tepco’s countermeasures may cause further disaster for the two reasons below,
1. The shaft / trench is probably leaking as well
From the sampling data taken on 7/31/2013, the retained water in the shaft is also significantly contaminated.
They measured 950,000,000,000 Bq/m3 of Cs-134/137 and 520,000,000,000 Bq/m3 of all β to include Strontium-90 at 13m depth.
The chloride concentration was 7,500 ppm, which is very high. This means the contaminated water is being exchanged with seawater.
The highly contaminated water is leaking to the sea through underground.
It is entirely meaningless to discharge the water to the leaking shaft.
About the soundness of the facility, Tepco’s spokesman commented “They can’t tell if it’s leaking or not because they haven’t visually seen it, but the facility is designed to have high seismicity.”
The world would trust their words.
2. If the trench is stuck, pumped water would start overflowing on 8/11/2013
From the survey of 7/31/2013, the water level in shaft is already 13m from the bottom.
The shaft is estimated to be 20m deep. Based on the rough calculation, it can only stock additional 250~300m3 of water.
If they start discharging the water into the shaft, it will be full only within 2~3 days.
On the other hand, Tepco states they assume the shaft is connected to reactor2 turbine building.
The discharged water would go to the building through the trench to be purified with other water.
However, it hasn’t been confirmed if it’s actually connected to reactor2 turbine building.
If not, it would overflow on 8/11/2013.
Tepco changed groundwater level data to be “reference” from this week

Tepco didn’t measure the groundwater level from the evening of 8/1/2013 to the morning of 8/2/2013.
The groundwater level data has been “reference (lacking accuracy)” since then. The reason is not clear.
It is the data about two borings, No.1-2 and No.1-4, where the groundwater was rising quickly. Especially the groundwater level was rising the fastest in boring No.1-4, but this is the furthest from the planned pump.

Based on their “reference” data, groundwater is already 78cm deep underground.

In the press conference of 8/7/2013, Tepco announced they are going to start pumping up the rising groundwater from 8/9/2013.
The location is on the seaside of reactor2. They are going to start installation from 8/7/2013.
The pumped up water (0.18 m3/min) will be sent back to the trench shaft in the south of the pump. However, contaminated water is already accumulated in the trench, and it’s also beside the coastal line.
The area is approximately 3,200m2. It is assumed that all the groundwater can’t be managed only by one pump.
Tepco plans to install well points (4.6m deep) from North to South at every 2m from next week.

It is not clear if it’s groundwater or the direct coolant water.

The most urging issue in Fukushima nuclear plant is the rising groundwater level on seaside of reactor2.
Tepco stated they are going to pump it up from this weekend but it’s not decided how to treat the water.
If they stock the water in the tank, they would have to process additional 100~150 tones of contaminated water every single day.
It is estimated Tepco would run out of the storage facility by mid November.

Tepco may lose a part of the plant area.
This is the matter of the world.
However, Tepco hasn’t published the groundwater level data for 5 days.
The last data they published was the one of 8/1/2013. and it was only about one of the four locations.

If it’s following the trend in July, probably now it’s already 65cm underground.
I personally am doubtful about the feasibility of the installation of the pump because the bearing power of soil may be significantly deteriorated already.

It’s not only the groundwater level data that Tepco doesn’t publish, but also the state of progress of the impervious wall.
Tepco plans to build two lines of the wall. The seaside line was already completed, but about half of the land side wall remains incomplete.

The land side of the area is likely to have the groundwater near the surface of ground already.
If so, it’s impossible to build the wall because the chemical material needs soil pressure to solidify.

At this moment we are not informed of anything that really matters. Press seriously needs to demand Tepco the relevant data.

According to Tepco, the radioactive density jumped up on 8/5/2013 from this boring.
Cs-134 : 310,000 Bq/m3 (15 times much as 7/31)
Cs-137 : 650,000 Bq/m3 (15 times much as 7/31)
All β (including Strontium-90) : 56,000,000 Bq/m3 (47 times much as 7/31)

Tepco has not made an announcement about the reason.

Tepco was monitoring sea contamination beside Fukushima port only at 3 locations

Now that the contamination is spreading over the sea, Tepco is required to monitor sea water contamination more precisely.
However nearby the plant port, they have only three monitoring points outside of the port according to Tepco.
Two of the three monitoring points are close to the coastal line. In the 1km offshore radius area, they have just one monitoring point.
They state more monitoring points are planned to be set after 8/12/2013, but it’s still only three.
The marine monitoring points beside Fukushima nuclear plant port will be still only six.

At 8:00 AM 8/6/2013, the “steam” was observed coming up from reactor3 again.
Tepco published the press release and videos.
And from Energy News......
